Redbill. The Red-crested pochard(Netta rufina) is a beautiful duck originally from the area of Turkey and the Black Sea, nowadays scattered population breeds in western Europe. Since the 1990s it has been living in lake Garda. The male is unmistakable: its round head and its red bill make him look like an exotic bird, the female has more discreet colours. This duck feeds mainly on water plants and is quite silent. In the first photos above, a couple is resting in the calm water with a mirroring effect.
